To all whom it may concern.:

Be it known that I, EUGENE AMBRo'ZY, a citizen of the United States, anda resident of the city of New York, in the countyof New York andv Stateof New York, have 1nvented certain new and useful Improvements inConstruction of Marine Vessels, of which the following is aspecification. A v

The present invention relates to marine vessels, or in other words toships. c

It pertains more particularly to marine described in application for U.S. 4Letters Patent, Ser. No. 27,355, filed by me on the 11th day of May,1915. In the said application, a vessel is described, comprising anouter hull and 'an inner hull, which hulls have a common keel, uponwhich rests a longitudinal bulk-head. To the said keel are fastenedtransverse plates having 'disposed along their outer edges channel-`irons, which constitute the transverse frames ofthe said outer hull. Asecond lset of channel-irons isl secured to said plates and Saidbulk-head, forming the transverse Vframes of said inner hull. There arealso means provided for connectingand bracing the two hulls. The outerhull has an impenetrable or puncture-proof skin or sides.

The main object of the present invention is to generally improve theconstruction of marine vessels of the class described in the aboverecited application by providing also the inner Ahull of the vessel witha punctureproof skin or sides, and by dividing the space between the twohulls into transverse water-tight compartments.

lith these and other objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrange nient and constructionl of parts hereinafterfully described, pointed out in the appended claims and illustrated inthe accompanying drawings, it being understood that many changes may bemade in the size and proper-- tion of the several parts and details ofconstruction within the scope of the appended claims without departingfrom the spirit or sacrificing any of the advantages of the invention.

Figure 1 is a transverse section midship of a vessel constructed in'accordance with the present invention, the right-hand side of saidsection being shown incomplete in order to more clearly show theconstruction; Fig. 2 is a transverse section taken through a por tionofthe vessel on an enlarged scale, showing the bracing means between thetwo hulls thereof; Fio'. 3 is a section taken on line 3-3,

of Fig. 2; Fig. 4 is a section taken on line 4-4 of Fig. 2; and Fig. 5is a section taken on line 5-5 of Fig. 1.

In the drawin s, the numeral 10 indicates the keel of the vessel,extendingg as in all structures of this type, throughout the length ofthe vessel, and being made in the form of' an I-.beam, the lower flange11 of which 1s wedge-shaped in known purpose.

a'verticalbulk-head 12, extending f'rom stem to stern and. connectedwith the transverse' frames of the vessel in a manner hereinafter, to bedescribed. This bulk-head divides,

cross section for the well. Above the keel is disposed y generallyspeaking, the hull into two longitudinal compartments, which communicatewith each other through door-ways (not shown inthe drawings);y

The transverse frames of the vessel are each made of two substantially.L-shaped plates 13, the outer contours of which 'correspond, of course,to the respective transverse cross sections of the vessel. These plates,

which form the back-bones of the transverse frames, are disposed atsuitable distances from each other and are united with auxiliarytransverse frames, each comprising a pair of plates 14, the heights ofwhich extend only one or two floors or decks above the bottoms, whilethe plates 13 extend to the uppermost deck of the vessel. rEhe louteredges of the plates 13 and 14C are provided with substantiallyequi-distantly arranged' parallel slots 1G, the lslotsin the severalplates being in alinement with each other for a purpose hereinafter tobe described. These slots run at rightangles to the edge of a platewhere said edge is straight, and f in radial direction to" the curvewhere said edge is curved, as for instance at the bilgel Parallel totheouter edge of each plate 13 and adjacent to the slotted pontipn thereofis riveted to each face of the samea channeliron 17, for instance ofU-shaped cross section, said channel-irons extending into the spacesformed between the ianges of the keel and forming together with theplates lvthe transverse frames of the outer hullv of the vessel. ln asimilar manner are riveted to both faces of the plates 14 channel-irons18, constituting with the plates 11i auxiliary transverse frames. Themain and auxiliary :transverse frames are spaced apart by chaninel-irons 19, which abut against the keel and are riveted toth latter,and also to the channel-irons 17 and 18.

A substantial distance above the channel.

irons 17 and 18 there are riveted to both faces of each of the plates 13and 14 channelirons 20, said last named channel-irons rest-.

ing upon the upper flange of the keel and extending toward the sides ofthe vessel and thence upward, their outer ends being attached in anysuitable manner to the channel-irons 17 and 18. The channel-irons 20 arespaced apart by longitudinal channelirons 21, whlch abut against and areattached to the bulk-head 12 and to the said channel-irons 20. Inclinedbraces 22, in the form of channel-irons, are riveted to both faces ofthe plates 13 and' 14, their lower ends being connected with thechannel-irons 20 near to the inner ends of the latter, and

the upper ends of saidr braces being suitably provided in the plates 13and 14 substantially parallel slots 25 and 26, respectively, the slots25 running from the openings 24 at right angles to the longitudinal axesof the channel-irons 23, and the slots 26 at right angles to thelongitudinal4 axes of the braces 22. The channel-irons 20 are supportedby stringers 27, made in the form of composite I-beams, which rest uponthe transverse fra-mes 17 and 18. Struts 28 connect the channel-irons 20with the transverse frames 17 and 18 to further brace and strengthen theelements. The stringers 27 extend through the plates 13 and 14.

The transverse frames of the outer hull of the vessel are connected bylongitudinal frames, which are constructed in the following manner: Toboth faces of each of the plates 13 and 14, and between the slots 16therein, are attached angle-irons 29,

lwhich are` bent into substantially O-shape,

each of said angle-irons being disposed betw'een two' slots in the saidplates and having a flange 30, that is disposed at right angles to theplane of the respective plate. The longitudinal frames, in the form ofU-shaped stringers 31; have their ianges 32 disposed in the slot 16, towit: In each slot there are disposed the lianges of two adjoiningstringers, their -bases 33 being riveted to the flanges 30 of theangle-irons 29. The outer faces of these stringere are lin the sheathing35 man-holes 35, which are closed by covers in the usual manner. Thelongitudinal frames run throughout the length of the' vessel. Toproperly brace the longitudinal frames 31, there are provided brackets36, having the same configuration as the angle-irons 29 above described.The brackets 36 run in parallel relation to the angle-irons 29, aredisposedv within the U- shaped stringers and attached to the latter andto the sheathing 35. In order to strengthen the sheathing 35, there areangle- 'irons 37 attached to the inner face of the said sheathing, saidangle-irons running in parallel relation to the `channel-irons 17 and18.

The transverse frames of the inner hull are also connected bylongitudinal frames. These frames, denoted by' the numeral 38', are,like the longitudinal frames of the outer hull, made in the form ofU-shaped stringers, their flanges 38 being disposed in the slots 25 and26 in the plates 13 and14, and fastened to the said plates bysubstantially O-shaped brackets 40, which are carried by the plates 13and 14. rIo the inner faces of these longitudinal framesl is fastenedthe sheathing 41 of the inner hull, brackets 42 and angle-irons 43serving to brace the same, the brackets 42 being disposed within thestringers 38, and the angleirons 43 being attached to the inner face ofthe sheathing 41. In the sheathing 41 are provided man-holes 44, coveredin any suitable manner,` to permit access into the stringers 38 when theriveting work is being performed. The sheathing 41 abuts against theouter flanges of the channel-irons 23 and braces 22.

The vessel may be provided with any suitable number of decks, each ofwhich is formed by deck-beams 45, the inner ends of which are footed onstringers 46, which are attached to the bulk-head 12, while their louterends are connected by angle-irons 47,

or similar means, with the channel-irons 23.

'The deck-beams 45 are connected Aby longitudinal stringers 53.Immediately below each deck-beam is located between the' inner and outerhulls a bracing girder 54, comprising' in the case illustrated in thedrawings a plurality of horizontal plates 55, which are united, forinstance by transverse girders are secured, 'for instance by angleirons58 tothe stringere 38. Flush with the deck-beams 45 are lattached to thechannelirons 23 beams 59, resting upon the uppermost plates of thegirders 54, and being connected with transverse beams 60,that areattached to the stringers 38 and form con- The deckbeams 45 and 60 arecovered by a `suitable deck plating 61,in which may be provided thenecessary hatches, as usual.

Struts 62 connect the channel-irons 2O vvith one set of stringers 46,and struts 63 `the braces 22 with another' set of stringers 46, saidstruts serving to keep, in addition to the elements above mentioned, thesaid l. channel-irons and braces in proper relation tcthe longitudinalbulk-head 12 both therefore, the outer hull be penetrated,-

hull.

water will not reach the lowermost deckv 'against inner and outerpressure. Inasmuch las the sides of the outer hull and the chan--ynel-irons 20, which form, as will hereinafter appear, one of thebottoms of the vessel, are connected with the bulk-head, the pressure,to which they are subjected, is transferred t"o and taken up by thebulkhead. To the underfaces of the upper flanges of the channel-irons 2Qis riveted a sheathing 64, thereby forming an intermediate bottom of thevessel. between the bottoms of the outer and inner hulls thereof.

From the foregoing it appears that the vessel comprises an inner hul-land an outer hull, each of which has transverse frames and longitudinalframes. The longitudinal frames form for each hull an impenetrable wall,the sheathing 35, covering the inner face of the wall of the outer hull,dividing the said wall into a plurality of longitudinal water-tightcompartments, and the skin 41 upon the inner stringers, dividinglikewise the Wall of the inner hull into longitudinal water-tightcompartments. The bracing girdcrs 54 form longitudinal water-tightcompartments between the inner and outer hulls, and, inasmuch as theopenings 24 above described are vnormally closed by doors 65, thesecompartments are subdivided into transverse compartments. Should,

water will rush only into those compartments betweenl the two hullswhich are adjacent to the injured portion'of the outer Should theouter`bttom be injured,

inasmuch as the sheathing 64 forms, as above described, a false bottomV4between the two hulls. Inasmuch as this last named bottom and the bottomof the outer hull are properly braced land armored, as it were, by theStringer-s 27 and ,struts 28, it is almost impossible to stave in thesame. The two hulls being braced by the girders 54 and connected by thetransverse plates 13 and 14, cannot separate.
